Description of problem:

Trying to deploy overcloud on Liberty stable version https://trunk.rdoproject.org/centos7-liberty/current/delorean.repo fails on overcloud nodes.


Version-Release number of selected component (if applicable):



How reproducible:


Steps to Reproduce:
1. Install overcloud: openstack overcloud deploy --templates -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e ~/templates/network-environment.yaml -e ~/templates/storage-environment.yaml --control-scale 1 --compute-scale 1 --control-flavor control --compute-flavor compute --ntp-server pool.ntp.org --neutron-network-vlan-ranges tenant:1010:1020 --neutron-bridge-mappings datacentre:br-provider,tenant:br-tenant

2. heat stack failed status


Actual results:

Expected results:

It should deploy the overcloud.

Additional info:

If I upgrade my python-oslo-config package from http://trunk.rdoproject.org/centos7/current-tripleo/delorean.repo this error doesn't show up on overcloud nodes, so I guess python-oslo-config needs to be updated on those stable repos.
